ROTARY FlLTER.

SPECIFICATION formingpart of Letters Patent No. 743,652, dated November 10, 1903. Application filed October 80, 1902. $erial No. 129,431. (No model.)

To all whom it may concern.-

Be it known that LGEORGE MOORE,a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Rotary Filters; and I do hereby declare the following to be a full, clear,

filtering operation, cleansing the same by a washing operation, and-then dislocating from the surface of the same all solids collected during the filtering operation.

"With this and other objectsin view the invention consists, in combination with a suitable series of tanks arranged in a circle, of a filtering medium, means for successively inmoving it from said tanks, means for subjecting the filtering medium to a drawing action, and means for further subjecting said medium to a blowing action.

It further consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a diagrammatic view indicating an embodiment in elevation of the present invention. Fig. 2 is a similar view indicating the same elements in plan. Fig. 3 is a view in side elevation of a filter of the preferred construction, some of the filter-plates being shown in section for illustrating the arrangement of the filteringmedium.

In carrying out the present invention I preferably employ, as indicated in Fig. 1 of the drawings, a vertical hollow standard 1, divided intermediate its length by a suitable partition 2,any suitable compressed-air pump 3 communicating with the upper end of said standard, and any preferable type of suctionpump 4 is suitably connected with the lower end of the standard. The standard 1 is provided with a suitable connection 5,upon which it is rotatably mounted, the said connection communicating with pump 1 and being supported by any suitable bracket or other supporting means 6. The upper end of standard 1 is provided with a connection 7, similar in construction to connection 5, communicating through a tube 8 with the pump 3, whereby said standard is free to rotate upon its central axis and carry the device supported thereby, while at the same time maintaining established communication with the said pumps.

Surrounding the standard 1 are receptacles 9 andlO and a discharge-chute 11, forming-a circle about said standard. Extending from the standard is a bracket 12, provided at its outer end with a pulley 13 and intermediate its length with a second pulley 14:, adapted to receive and guide a cable 15, which cable has its inner end attached to a sliding block 16, slidably engaging the standard 1 and attached to a piston 17 of a cylinder 18. A cylinder 19 is preferably arranged in a lower horizontal plane than the cylinder 18 and has its piston 20 extending in the vertical plane of the cable 15 and carrying a pulley 21, adapted to engage said cable. The cylinders 18 and 19 are carried by the standard 1 and move therewith. Any suitable gearing (not shown) may be employed for rotating the standard 1, or the same may be rotated manually, asfound preferable. The outer end of cable 15 is attached to a bail 22, carrying a filter proper, which filter comprises a series of plates 23 23, each provided upon each side thereof with a gauze or metallic mesh 24, outside of which is secured a suitable strip of fabric 25, forming the filtering medium. At

the lower end of each plate is provided an a tube 31, leading into the section of standard 1 beneath said partition, whereby communication between either of the pumps 3 or 4 may be established with the filter by positioning of the valve 29.

In operation the tank or receptacle 9 is filled with the material to be filtered, and the tank 10 is filled with water. The filter proper suspended from cable 15 is lowered into the tank 9 by the upward movement of piston 20 and the downward movement of the piston 17, the same being eifected by the release of pressure from cylinder 19 and the admission of pressure to cylinder 18, the pressure being supplied and exhausted from said cylinders in any preferred and well-known manner. The standard 1 is rotated until the filter proper approaches the dividing-wall between the receptacles 9 and 10, when the piston 20 is caused to descend, pulley 21 engaging cable 15 and pressing a portion of the same downwardly, while piston 17 is caused to move upwardly, raising the inner end of the cable, and thereby lifting the filter proper out of tank 9. Continued movement of the standard 1 brings the filter proper over the receptacle 10, when the said filter is lowered thereinto in the same manner in which it was lowered into receptacle 9, standard 1 continuing its rotation until the filter approaches the partition dividing tank 10 from chute ll,when the filter is raised over the said partition and lowered into said chute, continued rotation of the standard 1 bringing said filterinto proximity with the chute 11 and tank 9, whereupon it is again raised and then lowered into tank 9, the operation being continuous and, as will be apparent, may be made to be automatic, depending upon the means for driving standard 1 and for controlling the action of the pistons 17 and 20. While the filter is moving through tank 9, over the partition between said tank and the tank 10, through tank 10, and over the partition between said last-mentioned tank and the chute 11 the valve 29 is turned to establish communication between tube 28 and tube 31, whereby a sucking or drawing action is produced upon the interior of the filtering medium, and during the travel of the filter across the chute 11 the tube 28 is caused to communicate, by means of valve 29, with tube 30, whereby a blowing action is effected for discharging the solids which may have collected on the outer surface of the filtering medium.

It will be obvious that although I have specified the details of the particular elements employed in a given embodiment of the present invention, yet it is not necessary to use the precise construction mentioned for accomplishing the results by the principle involved, and I shall feel at liberty to deviate from the minor details of structure to any extent within the spirit and scope of the present invention.

Although I have described one particular form of filter, it will be obvious that other for ms may be employed of any preferred construction suitable for the operation accomplished in the present invention.

The present application contains such claims only as are directed to the structure herein set forth,the moregeneric claims forthe means for introducingand removing the filtering medium into and from the material to be filtered and for producing a drawing and blowing action on the said mediu m being presented by me in a copending application which was filed on the 30th day of October, 1902, and designated by Serial No. 129,432.

Although I have illustrated cylinders 18 and 19 and described the operation of the parts thereby, it will of course be understood that I do not limit myself thereto, but may substitute electrical devices or other suitable power means.
